Federal prosecutors have notified a former deputy secretary of the interior, J. Steven Griles, that he is a target in the public corruption investigation of Jack Abramoff's lobbying activities, sources knowledgeable about the probe said.

The sources, who spoke on the condition of anonymity, said that among the possible criminal charges being investigated is whether Griles made false statements to the Senate Indian Affairs Committee in 2005 about job discussions Abramoff initiated while Griles was deputy secretary. Griles's attorneys did not return calls seeking comment yesterday.

When Griles folds, will he implicate former Interior Secretary Gale Norton?
